The secret about real world Java applications is they tend not to be very object oriented at all, in the way OOP is taught in textbooks.

Interfaces are very heavily used, along with dependency injection (boy, do Java programmers love their dependency injection).

Inheritance is now widely discouraged. "Java Beans" are everywhere, which are glorified structs breaking every single rule of encapsulation.

Java runs fast, is garbage collected, has great support for multithreading, great Unicode support, and many other advantages. But it's certainly not very object oriented, especially in the Alan Kay sense.
